CHICAGO, ILLINOIS METAL FRAME FOR ALL--PLASTER WALLS Application led .Tune 14,

My invention relates to frames for all plaster walls and particularly to van improvement on the construction disclosed in my co-pending application Seria-l No'. 259,-

433, tiled March 6, 1928.

An object of my invention is to facilitate the manufacture and installation of frames of this character, and to provide for relatively great stiffness without the use of a continuous angle extending from the floor to the ceiling, as in the construction disclosed in my said co-pending application.

To that end, I provide trame members in the form of deep channels suitably shaped at l5 the mouth ci the channels to receive ywood blocks, the rear portion of the frame element being of such shape that the maximum rigidity is assured. As means for attachment of the frame to the ceiling, I provide a telescoped channel member in the upper end of the vertical frame element, together with suitable means at the upper end of the extension for attachment to the ceiling.

My invention will be more readily understood` by reference to the accompanying drawings, in which- Fig. 1 is a perspective view of a frame constructed in accordance with my invention;

Fig.. 2 is a sectional view through the trame' at a point near the ljunction of the vertical and horizontal member, the plaster being shown in place; and

Fig. E is a similar sectional view taken at r a point near the floor.

ln the drawings, the frame is illustrated as comprising vertical members A, only one of which is shown and a horizontal member B. `The frame elements are in the form the main flanges 11, auxiliary flanges 12, and marginal flanges 13. The flanges 12 are oppositely diagonally positioned to provide a tapered or ilaring space, within which a similarly shaped projection 14C from the wood block 15 is received. Nails 16 are projected through the flanges 12 into the wood blocks. The blocks are ositioned at properly spaced intervals in t e length or the frame members and serve as means of oi deep channels having the web 10, withV 1928. Serial No. 285,268.

attachment for the wood trim. The outer edges or the marginal flanges 13 serve as plaster grounds; they also serve as stillening flanges and contribute to the production of a stable frame member.

At the lower end of the vertical frame members, I provide ears or straps 17, 18 adapted to rest on the i'loor and be secured thereto. At various points intermediate the height of the vertical members, I provide rearwardly projecting straps 19, welded to the web 10 of the frame member and adapted to be imbedded in the pla-ster and to act as anchors. Holes 2O are provided in the main flanges 11 to insure a plaster lrey. Latli 2l is shown which will be attached to the frame members by clips or wires that pass through the holes in the sides of the channel. f

At the upper end of the vertical members, I provide trame extensions C. These are of deep channel shape in cross section comprising a. web 22 and side flanges 23. This member is so proportioned as to tit snugly7 between the flanges 11 of the iframe member and in reverse relation, thusforming a box section at the upper end of `the frame. The member C extends upwardly to the ceiling and ears 2st are provided for attachment to the ceiling. Preferably the frame extension is welded in place and the apertures 12 eX- tend through the flanges of that member also. At the upper end, I provide channel shaped clips having a web 25 and side iianges 26 shaped to conform to the flanges 12 of iframe member. The clips are so positioned as to providea space constituting a soclret'between the webs 22,25, adapted to receive the vertical leg 26 of a bar of L-shape; the other leg 27 of which is welded to the web oi' the trame member` B. A brace 28 is welded at its ends to the legs 26, 27; the lower extremity of the brace being positioned to abut the top surface of the clip when the parts are in the position shownk in Fig. 1.

vThe parts are constructed entirely in the shop and shipped in knocked down condition. The workmen will assemble the frame by causing the `portions 26 of the member B to enter the sockets in the vertical members. The assembled frame is then raised and properly positioned, being thereafter permanently secured to the floor and ceiling,

5 by means of apertured ears provided therefor. The lath is then applied at one side or the other of the frame elements and the plaster added in the usual manner.

The frame Will be found to be very stiii1 and rigid and have extreme simplicity in the matter of installation.

I claim: l. In combination, frame elements 'composed of metal of channel shape, including vertical and horizontal members, an angular lmember 4telescoped Within the top endof a verticalmember and projecting upwardly for holding engagement with the ceiling, a clip mounted in the upper end of the vertical member, the clip and angular member being positioned in the channel to define a socket, and a projection from the horizontal fra-me member adapted to enter said soclret.

2. In a frame for all plaster Walls, the combination of vertical and horizontal frame elements, said elements being composed of a sheetof metal bent to provide a deep channel with a flaring entrance bounded by lateral flanges, an angular member seated in said channel at its upper end and adapted to project vertically into contact with the ceiling, means cooperating With said vertical member and said angular member to provide a socket, and means on the horizontal member adapted to entersaid socket to interlock said frame elements.

3. In frames for all plaster Walls, the combination of Vertical and horizontal frame members of generally channel shape, vver- 440 tical extensions from the vertical members,

adapted 'to extend and be connected to a ceiling, said extensions being in the form of channels, placed in reverse relation relative to the channels of the frames, clips in the 2upper ends of thevertical frame members,-extending across the channels' and positioned to provide a space between the clips and the extension channels, and' projections from the horizontal members of V'the frame adapted to enter the said spaces. v

4. In combination, vertical and horizontal frame members, means providing a sliding interlocking connection between the members at their intersections, said frame Vmembers beingv of deep channel shape with the channel opening into the' space between the frames, the channel flanges being flared outwardly and terminating in lateralflanges adapted to act as plaster grounds, and frame extensions `telescoped into and secured to the upper ends of the vertical ramejmembers and adapted to be secured to a ceiling.

' In testimony 'whereof I have aHi-Xed-my signature.
